The tasks performed by modern military aircraft are currently expanding, as they are solved both in the air and in the aerospace, at high altitudes and at high flight speeds. However, in this case, the use of turbojet engines operation on aviation kerosene is not possible because of the high temperatures of aircraft structural elements due to aerodynamic heating that leads to the destruction of kerosene and the impossibility of using it as fuel. It is necessary to search for alternative fuel options, one of which is cryogenic fuel. This article substantiates the possibility of using cryogenic fuel, in particular hydrogen, for aerospace plane engines. Hydrogen has higher energetic qualities compared to aviation kerosene. The necessity of cooling the air before it enters the engine at high flight speeds of the aircraft has been proved. A design of the heat exchanger for cooling the air entering the compressor is proposed, and a method for its thermal calculation is developed, which is necessary when designing the structural layout of aerospace plane propulsion system.
